One tends to fire small person smoking marijuana, say (6)
I believe the answer is:
stoker
'one tends to fire' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for stoker that I've seen before include "Someone who fuels a furnace" , "Bram --, Irish novelist" , "Irish author of Dracula, d. 1912" , "Fireman - Bram" , "Boilerman" .)
